Bjorn is a guard captain for the city of Hávindr. He appears towards the end of Chapter 1: The Fancy Menace, in which he is found guarding the outpost in the Boring Bay, north of Castle Aldrheim. After entering the outpost, he greets the players but the fortification is attacked by a forest troll known as Ygg. Captain Bjorn rushes into battle with the troll, and may be killed in the fighting

If Captain Bjorn survives, he will inform the players that he was sent to escort the players to Hávindr, but does not believe they require protection. He will then gift the players his axe.

Should the captain perish in the fighting, then the guard Hrolf will rush into the outpost and lament his death before directing the players towards Hávindr. The captain's axe may also be stolen from his corpse.
